We’ll also show you how to work with package.json to manage a project’s dependencies.
#Npm install package with version install
We’ll show you how to install packages in local and global mode, as well as delete, update and install a certain version of a package. In this guide, we’re going to look at the basics of working with npm.
It installs the packages you want to use and provides a useful interface to work with them.
This is where npm, the Node package manager, comes in. To make use of these tools (or packages) in Node.js, we need to be able to install and manage them in a useful way. Since then, a whole new ecosystem of Node-based tools (such as Grunt, Gulp and webpack) has evolved to transform the face of front-end development. Originally, it was intended as a server environment for applications, but developers started using it to create tools to aid them in local task automation. It’s built on the V8 JavaScript runtime and written in C++ - so it’s fast. Node.js makes it possible to write applications in JavaScript on the server. This is good for when you don't need a very specific version, but you want to keep your dependencies up to date with the latest patches and security vulnerability fixes.įor more info, check out Caret vs Tilde in step-by-step guide will show you how to install npm, and master common commands in the Node Package Manager (npm) command-line interface.
#Npm install package with version Patch
Since we prefixed the version with ~, NPM retrieved the latest patch version under the 4.16 minor version, which turned out to be 4.16.4. So, for example, if you want to use Express version 4.16, but the patch version isn't important, you can use the tilde to tell NPM to retrieve the latest patch version: $ npm install ~4.16.1Īdded 48 packages from 36 contributors and audited 121 packages in 3.02s This way you can specify a compatible package version, but still get the latest. Using either a caret ( ^) or a tilde ( ~) we can specify the latest minor or patch version, respectively. With NPM we also have other options for specifying the version of a package.
To do this, we can specify the version using the syntax npm install Continuing with our example above, we would execute something like this: $ npm install Īdded 48 packages from 36 contributors and audited 121 packages in 2.986sĪs you can see, NPM has installed the package we specified. In cases like this you'd probably want to install a specific version of the package that you know works, or that you know is "safe". When you run the install command like this, by default it retrieves the latest version of the specified package, which in this case is v4.17.1 (at the time of this writing).īut what if we need a different version? Maybe this latest version breaks a feature that we need, or maybe it has a security vulnerability that the maintainer hasn't gotten around to fixing yet.
#Npm install package with version download
It's main purpose, however is to help you download and install Node packages from its repository to your project.ĭownloading and installing a package is done using NPM's install command: $ npm install expressĪdded 50 packages from 37 contributors and audited 126 packages in 3.262s
NPM, or the Node Package Manager, is a powerful tool that allows you to easily manage dependencies, run scripts, and organize project metadata.
